Mo. Rev. Stat. § 67.1624

No guarantee is afforded by the program until sixty days after a member files a notice of intent to claim. Furthermore, the governing commission shall be required to make payments to a member only upon receipt of verifiable evidence of the actual sale of the guaranteed residence in accordance with the terms agreed upon between the member and the governing commission at the time the governing commission authorized payment. If a member rejects an offer for purchase which has been submitted to and approved by the governing commission, the governing commission or program shall not be liable for any future guarantee payment larger than that authorized for this proposed sale.
